Our Factories

Inside the Prolonged Hair Factories

Every strand we sell begins inside our facilities we operate exclusively, never outsourced, never shared, never open to another brand. Across our processing operations, a single bundle is tracked from donor intake through our proprietary line to final delivery. We are the only vertically-integrated hair extension brand that controls every facility in its chain, and this is where that promise is kept.

Our facilities operate on the Provenance-7 protocol — seven documented checkpoints between donor intake and final bundle, including our signature low-temperature "cold-seal cuticle lock" stage, applied identically across every site we run.
